The mesoporous materials such as α-Fe2O3, Fe2O3-Mn2O3, MnO2, Mn2O3, TiO2, etc were obtained by the impregnation of metal precursors within the cubic mesoporous silica, crystallization to metal oxides at desired temperature and subsequent silica removal using 1-2M NaOH aqueous solution. The mesoporous metal oxides thus obtained exhibit highly ordered cubic Ia3d mesostructure and high surface areas between 60-200m2/g. The framwork structures of the mesoporous metal oxides can be controlled by various factors such as metal precursors, heating temperature, heating period and so on. The characteristics of various Mesoporous Metal Oxides were comfirmed by XRD, HRTEM, FESEM, and N2 sorption. |
